EUB that sounds like a fretless

I play upright. I have tried to play the horizontal bass, but can't get the fingering down. However, I like fretless bass sound and the mwah. Is there a EUB that would be a similar scale as an upright that would have a fretless bass sound?

I don't own one, but I tried and NS the other day at a local music store. The one I tried had the optional EMG magnetic pickups. When using the magnetic pickups, it made it sound more like a fretless than upright to me.

I'm gonna get slammed by the DB guys cuz I think they consider it a toy, but I've got a Dean Pace and it definitely has the fretless sound. Lots of mwwwaahhhh... almost too much, and a great price tag. I got mine about a year ago and I love it.

Francois - Are there any particular Spirocores you would suggest as being the best for giving an NS CR4 a very "fretless" sound? I am looking for that sound for a particular project and don't have a fretless BG (did have once but didn't get on with it). I searched on 'Spirocores' but didn't really find an answer to this question. You mention that you use them but it seems you use a mixture? Thanks.

Either the Weichs or regulars.
The solos are darker sounding.
The starks could be another choice, but they're quite stiff!

I only have one Thomastik string left on my EUB, the E.
I had a solo Spiro one for a while, and yesterday I put on a Superflexible.
I have a couple of other E's to try until I decide if I put the solo spiro back on.
